Just read Old Man's War
by John Scalzi. I enjoyed it, some interesting concepts, but it clearly owes credit to Heinlein (mentioned in the acknowledgements) and Haldeman for some inspiration. My biggest peeve with the book was the way-too-witty dialogue. Reminded me of the nausea-inducing dialogue that Orson Scott Card has been writing for the last ten years. Good book otherwise, and looking forward to the sequels.
Now reading Frankenstein
, and discovering how much license the film industry has taken with the story.
